Jack Mack has learned a lot about the heroin epidemic ravaging the nation ever since his son became one of its victims. Casey Mack, 24, succumbed to a heroin overdose on Labor Day in 2012. Mack, of Croton, has since become an advocate for changing state laws to reduce such fatalities. Chief among them has been increasing access to an antidote that could prevent overdose deaths from heroin and other opioids including oxycodone, fentanyl and morphine. Thursday's announcement by state Attorney General Eric Schneiderman to equip state and local police officers with naloxone, the antidote that would allow them to treat overdose victims at the scene, is a major step, Mack said, in the battle against the drug scourge.
